_Bush's daughter, B_. In 1914 Bush (5) reported upon the mental examination of his daughter, B, who at the age of 3 years 6 months tested at 6 years by the Binet tests of 1911. Her IQ would thus be proved at about 185, calculated from her father's detailed record of responses. This report was rendered primarily to show that the Binet tests were too easy, as no child could possibly be really so advanced mentally as was B. "B's state is in no wise extra-normal, or beyond what it should be. She represents the norm." Additional data concerning B are that she "is of a happy disposition . . . strong and well of body," and that her parents are both teachers. This record clearly reveals a child of surpassing intelligence, contrary to the father's belief that "she represents the norm." _Elizabeth, recorded by Langenbeck_. In 1915 Langenbeck (15) contributed observations of a 5-year-old girl, Elizabeth, who tested at a mental level of about 11 years by the Binet-Simon tests of 1911, administered in the Psychological Laboratory at John Hopkins University. This would yield an IQ of about 220 (assuming the tests of 1911 to be approximately comparable with Stanford-Binet in power to distribute intellect). Elizabeth is described as an only child. At 16 months she had a speaking vocabulary of 229 words, some English and some German, as she had a German nurse. At 5 years of age she had a speaking vocabulary of 6837 words, which are inscribed in the record. The observer writes of her as follows:
